triangular membranous finely incise-serrate. E. B. 224. H. F. 

 49. X. 353. St. long. Branches short, ascending. Spikes on 

 long stalks, pale yellow. Scales on the ped. irregularly disposed 

 in whorls. Heaths. P. VII. VIII. Common Club-moss. E. S. I. 



2. L. annot'inum (L.) ; 1. loosely scattered lanceolate mucro- 

 nate serrulate, spikes sessile solitary terminal, scales roundish 

 shortly acuminate membranous and jagged. E. B. 1727. N. 

 361. St. very long. Branches rather long, erect, each year's 

 o-rowth marked by a constriction. Spikes cylindrical, greenish 

 yellow, not persistent. Stony mountains. Very rare in Caer- 

 narvonshire and Cumberland. Common in the Highlands of 

 Scotland. P. VIII. E. S. 



3. L. alpinum (L.) ; 1. in four rows, imbricate acute keeled 

 entire, spikes sessile solitary terminal, scales ovate-lanceolate 

 fl.it, branches erect clustered forked level-topped. E. B. 234. 

 H. F. 53. N. 365. St. long prostrate; also a subterranean 

 rhizome. Fertile branches usually twice dichotomous, each di- 

 vision ending in a short cylindrical yellowish-green spike rather 

 thicker than the branch. [Large forms with flattened br. have been 

 mistaken for L. complanatum (L.) 5 which may be distinguished by its 

 conspicuously stalked spikes, which are usually not solitary, and its more 

 linear 1.1 Stony moors. P. VIII. Savin-leaved Club-moss.

4. L. inunddtum (L.) ; 1. secund linear subulate, spikes ter- 

 minal sessile leafy solitary upon short erect branches. E. B. 

 239. H. F. 51. N. 369. St. short, prostrate, rooting. Branches 

 few, simple, fertile. Bracts subulate from a dilated base. F 

 heaths. P. VIII. IX. E. i 



** St. decumbent below, then erect. Caps, in axils of upper leaves 

 solitary. No spikes. L. all alike. PLANANTHUS Palis. 



5. L. Seldgo (L.) ; I. in eight rows crowded uniform linear- 

 lanceolate acuminate, caps, not spiked but in the axils of the 

 common leaves, st. erect forked level-topped. E. B. 233. H. F. 

 54. N. 375. St. short, erect or slightly decumbent, densely leafy. 

 No separate spikes. At the extremity of the stem a few curious 

 viviparous buds may usually be found ; they are well illustrated 

 by Mr. Newman (p. 378). Occasionally the stems in sheltered 

 situations become much lengthened. Heaths, chiefly on moun- 

 tains. P. VI. VIII. Fir Club-moss. E. S. I.
